Experimental Investigation to Study the Effect of Micro Coated Tool on the Surface Topology of Hard to Machine Materials


The traditional method of machining the hardened steels includes rough turning, heat treatment, and then grinding process. However, in the light of multitude influences of coatings on the contact and tribological phenomena, the choice of coating compound and its structure should be tuned to the specfic tool workpiece combination and process conditions Recently, machining of hard to cut materials using micro coated tools is an emerging technology and an attractive alternative to conventional grinding due to its potential benefits such as short cycle time, process flexibility, higher material removal rate, compatible surface roughness and less environmental problems. Several experimental investigations have to be carried out in order to study the effects of cutting parameters and machining time, the influence of workpiece hardness, tool geometry, micro coated tool materials and cutting fluid on machinability. As Gujarat is a state which is flourishing with new industries this kind of a project will help in setting the standards for machining of hard to cut materials which have been utilized for manufacturing parts of automobiles, railway vehicles, Gears, Tools and dies etc. Moreover, this study will produce an alternative to hard turning in the form of turning using micro coated tools for checking the surface morphology of the workpiece material as well as the tool life. It is suggestive from the literature that the concept of hard turning using micro coated tools has gained considerable attention in the recent past in metal cutting as it can apparently replace the traditional process cycle.
